1 Agenda

• The City of Vienna in ICT - numbers • History of Open Source in Vienna • OSS on servers • OSS on the desktop – Study STOSS – WIENUX & OpenOffice.org2 • Examples • Legal aspects • Lessons learned • Questions?

© City of Vienna - Peter Pfläging 2 The city of Vienna in ICT numbers • 62.000 civil servants • 470 employees in the ICT department • 1 Host system (IBM zOS) • 3 SAP systems (SAP, Oracle, AIX and RedHat i386) • 700 application- & fileservers (Unix/Linux or Windows 2003 Server) • 300 connected networks = locations in Vienna • 20.000 PC‘s as workstations & 12.000 PC‘s in schools • 7.500 network printers • 900 notebooks • Ca. 350 applications (8.000 components) • 40.000 telephones & 1.100 cell phones

1991: City of Vienna in the internet with TCP/IP Development environment for Unix with GNU Open Source

1993: First internal webservers

1994: Samba as fileservers for the City of Vienna

1998: Start migration FreeBSD -> Linux (Kernel v.2)

2003: First large open source project from the City of Vienna (vieW4 - web collaboration)

2004: Study STOSS => Linux on workstations. Start development WIENUX (Debian Sarge)

2005/Q3: WIENUX shipment starts, OpenOffice.org2 for the City of Vienna is ready.

2005/Q4: Decision OSS DB: PostgreSQL

2008: Switching from Debian to Ubuntu on the Desktop

• Thinking of the “Linux Desktop” since 2001 (yearly location decision) • Base: Operating system and office suite are productiv and stable • Political motivation from Munich

• Detailed study as project STOSS – Q4/2003 - Q3/2004

– (STOSS means “STudie Open Source System”)

• Conclusion: – 1.100 SW products installed – 7.500 PC’s without MS-Office dependency – 4.800 PC’s without MS-Windows dependency

• 3 scenarios: – MS-Windows & MS-Office – MS-Windows & OpenOffice.org2 (7.500 PC’s) – Linux & OpenOffice.org2 (4.800 PC’s)

• Technical aspect: – Integration of Linux & OpenOffice.org2 – Coexistence of 2 platforms • Economical aspect: – “gentle” migration path: •OpenOffice.org2 as “second option” • WIENUX workstation in parallel to MS-Windows – Customers can decide! – WIENUX is cheaper!

• OpenOffice.org2 for MS-Windows (rollout since Q3/2005) • Product: WIENUX workstation (since Q3/2005) – Ubuntu 7.10 – Gnome 2.2, SAP GUI, Java, Open Office, Firefox – Kerberos V Logon to MS-AD, LDAP • Support for the private use of OSS products • As of Q4/2007: – WIENUX: 1.000 installations – OpenOffice.org2 for MS-Windows: 15.500

• VMS Emulation on Linux Servers – Bringing old Application back to life on new HW • Open Source SW on Desktops: – OpenOffice – Freemind – PDFCreator • Signing PDF‘s with PortableSigner – Programmed from us for the community – http://portablesigner.sf.net/ • Open Source Frameworks for e-Government – .NET and Java

• Using OSS: – Documentation of the use and deployment – Clarify support options before deployment • Creating OSS: – Decision on License: GPL for us! • no chance of spoiling the IT - market – Liability can be a problem in europe • Procurement: – Problem: you cannot buy OSS => buy support! – It’s not allowed to force OSS in procurement!

• “Clear Box” versus “Black Box” – Level of understanding is better – Easier search for bugs and errors

• OSS product selection is not always easy

• OSS = integration platform

• If your knowledge in the organisation is good, it’s easier to use OSS

OSS means local revenue

OSS means Open Standards
